Answer:

The car is going 45 mph

Step-by-step explanation:

Since the speed limit is 35 mph and the car is 10 mph over the speed, we can add them to find out how fast the car is going. We can solve 35+10 which will give us 45. So it is not a sum of 0 but instead a sum of 45.

(hope this helped)

Answer:

35+10 =45

Step-by-step explanation:

add 10 to 35 then divide by 2

Answer:

B.x<0 cs u useing easy steps

Answer:

x=2

Step-by-step explanation:

25/625 is 1/25

1/25 = 1/5^x

1/5 =sqrt 1/25 and that is 2

so x=2.

Answer:

54 km/h

Step-by-step explanation:

Step one:

given data

We are required to perform unit from m/s km/h

from 15m/s to km/h

Step two:

1 meter= 1/1000 km,

1 seconds= 1/3600 hour

1m/s = 1/1000/1/3600= km/h= 3600/1000= 36/10= 18/5 km/h

so of 1m/s is equivalent to 18/5 km/h

then 15m/s is equivalent to x

cross multiply

x= 15*18/5

x= 3*18

x=54 km/h

Answer:

D. 2787.64 yd^3

Step-by-step explanation:

This is the formula for the volume of a cone:

[tex]V=\frac{1}{3} \pi r^2h[/tex]

The height of the cone is 22 yd. The radius of the base of the cone is not given but we can use the diameter to calculate it since the radius is equal to half of the diameter.

[tex]r=\frac{1}{2}d\\r=\frac{1}{2}(22)\\r=11yd[/tex]

Therefore, the radius of the base of the cone is 11 yd.

Now, we plug our values into the formula and solve.

[tex]V=\frac{1}{3} \pi r^2h\\V=\frac{1}{3} \pi (11^2)(22)\\V=\frac{1}{3} \pi (121)(22)\\V=\frac{1}{3} \pi (2662)\\V=\frac{1}{3} \pi (2662)\\V=2787.64 yd^3[/tex]

Therefore, the volume of the cone is equal to 2787.64 yd^3.

I hope this helps!

Answer:

[tex]\mathbf{ \dfrac{dr}{dt} = 0.03730 \ cm/min}[/tex]

Step-by-step explanation:

The rate of the inflation of the balloon with time can be denoted as:

[tex]\dfrac{dv}{dt} = 500 \ cm^3/m[/tex]

To determine; how fast does the radius change with time.

i.e.

[tex]\dfrac{dr}{dt}=???[/tex]

where r = 40 cm and the volume of sphere = [tex]\dfrac{4}{3} \pi r^2[/tex]

∴

[tex]\dfrac{dv}{dt}= \dfrac{4}{3} \pi 2(r^3) \dfrac{dr}{dt}[/tex]

[tex]500= \dfrac{4}{3} \pi \times 2(40^2) \dfrac{dr}{dt}[/tex]

[tex]500= 13404.13 \dfrac{dr}{dt}[/tex]

[tex]\dfrac{500}{13404.13} = \dfrac{dr}{dt}[/tex]

[tex]\mathbf{ \dfrac{dr}{dt} = 0.03730 \ cm/min}[/tex]

Answer: 300

Step-by-step explanation:

Answer:

Terms: -8, -4c, 7, -c, -12c, -2

Variables: c

Coefficients: -4, -1, -12

Constants: -8, 7, -2

Step-by-step explanation:

Terms are anything in between a plus or minus.

Variables are anything that is not a real number, such as c.

Coefficients are the number directly before a variable, such as -4 in -4c.

Constants are any real numbers without a variable, such as -8.

Answer:

Concept: Numerical Analysis

Answer:

1/50 as far

Step-by-step explanation:

6.8 x 10[tex]^{16}[/tex] ÷ 3.4 x 10[tex]^{18}[/tex]

Rules state that you divide numbers and subtract exponents

6.8/3.4 = 2

10[tex]^{16}[/tex] ÷ 10[tex]^{18}[/tex] = [tex]10^{-2}[/tex]

whenever exponent is negative, it gets turned into a fraction with 1 as the numerator and the exponent will become positive when placed in the denominator

10^-2 = 1/10^2 which is the same as 1/100

2 multiplied by 1/100 = 1/50

Answer: U = 18

Step-by-step explanation:

U in (-oo:+oo)

U/(-6)+2 = -1 // + 1

U/(-6)+1+2 = 0

3-1/6*U = 0 // - 3

-1/6*U = -3 // : -1/6

U = -3/(-1/6)

U = 18

U = 18

Answer:

-3 (-6u+6) - u = 2 (u-6) - 1​

18u -18 -u = 2u -12 -1

18u-u-2u=-12-1+18

15u= 5

u =5/15 = 1/3

Step-by-step explanation:

Answer:

A) 5

Step-by-step explanation:

(5^(1/3))^3=5^(1/3*3)=5^(3/3)=5^1=5

Answer:

h = 64 feet

Step-by-step explanation:

If you graph the function you see that 64 feet is the maximum of the parabola so this is the max height that the projectile reaches.

Answer:

E D C are the answers for the questions

Answer: W is the correct answer just for clarification.

Step-by-step explanation:

Answer:

The answer is "The first choice"

Step-by-step explanation:

In the given question the first choice is correct because When the zero assumption was valid, it would have been at least as bad to also be 2% to demonstrate a discrepancy as observed difference.

The answer is 60 or 15 because you need to have 150 for a triangle

Sorry I couldn't help too well!

Hope this helps!! Brainliest is appreciated!! Happy Holidays!!!

Answer:

a = ±sqrt(3)

Step-by-step explanation:

a×a×a=a+a+a

Simplifying each side

a^3 = 3a

Divide each side by a

a^3 /a = 3a/a

a^2 = 3

Take the square root of each side

sqrt(a^2) = ±sqrt(3)

a = ±sqrt(3)

Answer:

nope its not equal

a×a×a=a³, but a+a+a=3a

so, a³≠3a

Step-by-step explanation:

i hope this helps....can i have brainliest

MERRY CHRISTMAS!!!......ENJOY UR HOLIDAY!!!

Answer:

Step-by-step explanation:

I don't know what you were supposed to do with 3 but 4 looks much easier.

It's telling you to increase the side lengths by a factor of 3y

4x(3y) + 4x(3y) = 3y * 3y

12xy + 12xy = 9y^2

Perimeter = 24xy + 9y^2

I can't see anything else to do with this question. If you think I've misread it or there is more to it, leave me a note.

Answer:

x ≈ 27.2

Step-by-step explanation:

Using the sine ratio in the right triangle

sin54° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{22}{x}[/tex] ( multiply both sides by x )

x × sin54° = 22 ( divide both sides by sin54° )

x = [tex]\frac{22}{sin54}[/tex] ≈ 27.2 ( to the nearest tenth )

Answer:

Thus, [tex]y=-\sqrt{x+3}[/tex] represents the transformed graph on the attached figure, which is a translated square root graph i.e. vertically reflected across the y-axis and also horizontally translated or shifted 3 units to the left.

Step-by-step explanation:

Consider the function

y = f(x)

The rule of horizontal translation

y = f(x-h)

When 'h' is positive, the function is shifted to the right.

When 'h' is negative, the function is shifted to the left.

The rule of implying vertical reflection across the x-axis

y = -f(x)

Applying the rule:

We know that the square root function is

[tex]y=\sqrt{x}[/tex]

We know that if the graph would be reflected across the x-axis, then

[tex]y=-\sqrt{x}[/tex]

We know that   is horizontally translated or shifted 3 units to the left, it implies  +

3 inside the radical implies. Then the transformed function becomes .

Please check the attached diagram. From the diagram,

Thus, [tex]y=-\sqrt{x+3}[/tex] represents the transformed graph on the attached figure, which is a translated square root graph i.e. vertically reflected across the y-axis and also horizontally translated or shifted 3 units to the left.
